4. Press the Add X-Axis softkey.
ª The instrument makes the measurement and confirms this with a
short beep. The number of averaged values (No. of SAVG) still
indicates 0. The instrument continues measuring in the background
(indicated by No. of Runs) but does not use these values for
determining the average.
Note: The measuring antenna must not be moved during the
measurement, i.e. from the time you press the Add Axis key until the
beeper sounds.
5. Orient the antenna in the direction of the Y axis and press the
Add Y-Axis softkey.
ª The instrument makes the measurement and confirms this with a
short beep. The number of averaged values (No. of SAVG) still
indicates 0. The instrument continues measuring in the background
(indicated by No. of Runs) but does not use these values for
determining the average.
6. Orient the antenna in the direction of the Z axis and press the
Add Z-Axis softkey.
ª The instrument makes the measurement and confirms this with two
beeps. The number of averaged values (No. of SAVG) now indicates
1 because the isotropic measurement for the first measurement point
has now been completed. The instrument continues measuring in the
background (indicated by No. of Runs) but does not use these values
for determining the average.
7. Move the antenna to the next position in the room to be measured and
repeat the process for the X, Y, and Z axis positions.
ª The number of averaged values (No. of SAVG) now indicates 2. The
instrument averages the two isotropic results and displays the overall
result numerically. The instrument continues measuring in the
background (indicated by No. of Runs).
8. Repeat the process for all of the points in the room that are to be
recorded.
